drm/amdgpu: don't do resets on APUs which don't support it
It can cause a hang. This is normally not enabled for GPU
hangs on these asics, but was recently enabled for handling
aborted suspends. This causes hangs on some platforms
on suspend.
Fixes: daf8de0874ab5b ("drm/amdgpu: always reset the asic in suspend (v2)")
